The onset of lymphangiomas is either at birth (60% to 70%) or up to two years of age (90%) and rare in adults. These malformations can occur in any region of the body, Lymphangiomas have marked predilection for the head and neck region (50% - 70%). The most common location in the mouth is the dorsum of tongue. If the positive diagnosis is generally easy, the therapeutic management remains controversial. We report the clinical case of a 23-year-old adult patient with cystic lymphangioma on the floor of the oral cavity extending gradually to the right submandibular region. The clinically suspected tumor was thoroughly explored using tomodensitometry. The treatment consisted of complete resection by a cervicotomy with histological examination confirming the macroscopic diagnosis of cystic lymphangioma. Follow-up at 3 years showed no recurrence.展开更多

For the radiation of sunlight is identical in the same unit area of the same latitude, we could not increase the productivity by changing the total radiation, but we can change the property of the floor by setting up effect be1ts and develop the structure of community and the photosynthetic system. In the end, significant benefits on productivity and biological, ecological effects were showed by 30 years experiments.展开更多
